The five-member commission, which oversees utilities in the state, has put the issue on its agenda for the upcoming meeting in Albany.

National Grid's accounting issues came up several years ago during the company's previous electricity rate hike request. The PSC's review of the company's expenses found a wide range of issues with company spending that should not have been earmarked for consumers to pay. Pending a lengthy review by a Kansas-based firm called Overland Consulting, the PSC made $50 million of National Grid's electric rates in upstate New York "temporary" so that it could be recouped should the review conclude the money belonged to consumers.

The Overland audit was originally scheduled to cost $1.76 million, although completion of the study has taken longer than originally expected. It is unclear if Overland has completed the audit and if the PSC has reviewed the findings. As a rule, the PSC does not comment on agenda items before meetings are held.
